  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Short - faced; breeds including Boston terriers - pugs - English bulldogs - and Pekingese.






2. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






3. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






4. The bones of the tarsus - consisting of two rows of short bones located between the distal ends of the tibia and fibula and the proximal ends of the metatarsal bones.






5. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






6. The joint between the pelvis and the sacrum that joins the pelvic limb to the axial skeleton.






7. The paranasal sinus in the ethmoid bone of horses and humans.






8. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






9. Skull bones that are part of the internal bones of the face; support part of the lateral walls of the pharynx.






10. Large - multinuclear cells of bone that absorb bone and structures and reshape or remodel damaged bones.






11. A hole in the bone.






12. The last - most caudal sternebra; the _____ process.






13. The end of a long bone; each long bone has a proximal and distal _____.






14. Rib whose costal cartilage directly joins the sternum.






15. The kneecap; the largest sesamoid bone in the body; located on the front surface of the stifle joint in the tendon of the large quadriceps femoris muscle. It rides in the trochlea of the femur.






16. The joint composed of the tarsal bones; referred to as the hock in most animals and the ankle in humans.






17. The bone in the neck region that supports the base of the tongue - the pharynx - and the larynx - and aids the process of swallowing. It is usually referred to as a single bone - but it is composed of several portions of bone and cartilage.






18. The upper arm; the area of the thoracic limb between the elbow and the shoulder.






19. Bones of the forelimb that lie between the carpals and phalanges of quadrupeds.






20. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






21. The collective name for 37-38 bones of the head; it houses the brain and all the special sense organs.






22. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






23. Tiny channels through the matrix of bone. Threadlike projections from osteocytes communicate with each other and with blood vessels through these structures.






24. The first - most cranial sternebra.






25. One of the irregular bones of the spinal column.






26. A slightly movable cartilaginous joint - such as the pubic symphysis.






27. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.






28. The cranial portion of the dorsal body cavity formed from several skull bones; it houses and protects the brain.






29. A joint movement that consists of a twisting motion of a part on its own axis.






30. A beak - shaped process at the proximal end of the trochlear notch of the ulna; when it fails to unite with the ulna - an ununited process can cause the elbow joint to become unstable - leading to lameness.






31. The most caudal rib or two in the rib cage; a rib whose costal cartilage does not unite with anything but rather ends in the muscle of the thoracic wall.






32. The growth plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. They are areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full adult






33. Also called a spheroidal joint - it consists of a spherical joint surface (the ball) that fits into a closely matching - concave joint surface (the socket). Examples: shoulder and hip joints. Capable of all synovial joint movements.






34. The joint composed of the carpal bones; referred to as the 'knee' of the horse and the 'wrist' of humans.






35. The bones of the pelvic limbs located between the tarsus and the phalanges.






36. An alternate name for joint cavity.






37. The smooth joint surface of a bone that contacts another bone in a synovial joint.






38. Skull bones; external skull bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs - which are part of the tear drainage system of the eye.






39. Long - faced. Example: Collie.






40. One of the three ossicles in the middle ear; also called the stirrup - it is attached to the oval window of the cochlea and is the innermost of the three ossicles.






41. A toe made up of two or three boens called phalanges.






42. The fluid - filled potential space between the joint surfaces of a synovial joint; normally filled by synovial fluid.






43. The fibrous membrane that lines the hollow interiors of bones.






44. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






45. The epiphyseal plate of a long bone; located at the junction of the proximal and distal epiphyses with the diaphysis. Areas where long bones increase in length by the process of endochondral bone formation. When an animal reaches its full size - thes






46. A skull bone that is one of the external bones of the cranium; the caudal - most bone of the skull that forms the atlanto - occipital joint with the first cervical vertebra through the occipital condyles. The large foramen magnum in the occipital bon






47. The solid structure formed by the fusion of the sacral vertebrae.






48. The most caudal of the three pairs of bones that make up the pelvis.






49. A pair of large holes in the pelvis located on either side of the pubic symphysis; the role seems to be to lighten the pelvis because no large nerves or vessels pass through them.






50. The fibrous membrane that covers the outsides of bones except for their articular surfaces.
